Dr Conrad Murray, physician to the late Michael Jackson, has spoken out for the first time since his death, claiming he has told nothing but the truth in a new YouTube.com video.

Reports suggest Los Angeles prosecutors are trying to build a manslaughter case against the physician, who was staying at Jackson's Holmby Hills home in California when the pop superstar died on 25 June (09).

But Dr. Murray insists he did nothing wrong, and told police detectives interviewing him about his famous patient's last night everything.

A tired-looking Murray looks straight into the camera and says, "I told the truth and I have faith the truth will prevail."

The doctor, who has been in hiding since Jackson's death, used the one-minute YouTube video to thank patients and friends for their support.

The video comes days after the Los Angeles Times reported Dr. Murray left a sleeping Jackson, who was under the influence of a powerful anaesthetic, alone so he could make telephone calls. Sources claim the King of Pop had stopped breathing by the time he returned.

Murray has been identified in court records as a suspect in a police manslaughter investigation.
